Q: capacitive touch is not touch screen readout for TFT ?
A: It is possible to enable and operate capacitive touch on a TFT LCD depending on the nature of the physical touch construction. For instance, if you have ITO as discrete locations on the screen, it is possible to decern which location is being touched. This would not necessarily include a multi-touch experience unless the designer wants to extend the capabilities beyond today's firmware release. Most TFT, ITO screens we see already come with an attached device to handle capacitive touch down to the pixel level.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
